The conversation rate is c+273=k
All of these metals from cations, so they lost electrons when forming ions. The answer is D.
Bond energy refers to the energy that must be taken in to break a bond. It is also the energy required to form the bond.
<h3>What is Bond energy?</h3>
The term bond energy refers to the energy that must be taken in to break a bond. It is also the energy required to form the bond.
The energy that must be supplied to break the bonds in two molecules of HCl is 862 J. The energy released is obtained from; 862J - [436 +262] = 164J.
The total energy of the reaction is 164J, this is called the enthalpy change. Based on this value of the total energy, the reaction is endothermic. Hence, it is true that; "It takes more energy to break the two H–Cl bonds than is released when forming the H–H and Cl–Cl bonds."

Answer : b. mixture
<h3>Further explanation</h3>
Element and compound are included in pure substance where the composition is the same in each part
Elements are made up of 1 type of atom, while the compounds of 2 or more types of atoms
, both can be represented in the form of chemical symbols
A mixture is a combination of substances. The properties of a substance in the mixture component are unchanged
The mixture can be a homogeneous mixture or a heterogeneous mixture
- the homogeneous mixture if each part has the same composition
- the heterogeneous mixture if each part has a different composition
Solution including into Homogeneous mixture, while suspension into a heterogeneous mixture
So a term that could refer to heterogeneous matter : b. mixture
